Welsh musician Gruff Rhys documents his latest musical road trip, retracing the fantastical adventure of his 18th Century relative, the explorer John Evans.

In search of a lost tribe of Welsh-speaking Native Americans, John Evans left Wales for America in 1792 with only a $1.75 in his pocket. Alone and without a horse, he walked into the wilderness of the Great Plains and reappeared 7 years later as Don Juan Evans having changed the shape of American history. [Synopsis courtesy of SXSW]
